Title: Quasi-isochronous storage ring for enhanced FEL performance

Abstract

A compact storage ring is designed to be used as a driver for an FEL. This ring can be operated very close to zero momentum compaction factor ({alpha}) to increase the electron density and thus the gain of the FEL. In order to control {alpha} with zero dispersion in the straight sections the authors use an inverted dipole located between the bending magnets and 4-families of quadrupoles. By using 3-families of sextupoles they can control the 2 transverse chromaticities and 2nd order momentum compaction. They find that the ring has sufficient dynamic aperture for good performance.
